I also used magnifying Glass to repaint my face.
The eyes, the black halo around the eyes and silver parts, all needed repainting.
Remember to add some clear yellow on the golden eyes, the outlook would be better
Not only the color tone, I think the thinner to paint ratio may too high too. You can add some more thinner for trial, it should be easier for imbibition.
Those lines are not done by drawing.
They are done by imbibition.
Thinner > paint, then allow the thinner paint mixture to flow by itself.
Then the mixture will follow the tracks, only by this way the lines could look thin and sharp, otherwise they will look odd.
